Question - TE25 - Frame Rate Conversion from 23.976 to 25fps No.32081
Hiddendragon  Home )  2002-12-18 15:45:02 ( ID:lpwgxokawr. )   [ Delete / Reply with quotation ]

I got about 150 avi movies on my HD that i want to convert to vcd's . But when i do this i keep getting frame skips or a frame hitch ( dunno how you call it ) but the image is not fluent. Can someone explain me how i can get the image fluent , i am using tmpgenc now.But if someone has advice about using another program plz let me know. If you know how to solve this can you also explain how i have to do this.

Thx guys

Well the answer to Why you are getting the "Jumpt Playbeck" is in the Title of your Post...Tmpgenc Can"t properly convert Frame rates ,there is an AVISYnth script command that is supposed to convert the framerate for you while Frameserveing..and there are Programs that do NTSC/Pal conversions Like "ProCoder" and "Advanced NTSC/Pal Converter" But you would be better off useing AVISynth cuz it would be much faster....


B_Racer  2002-12-18 23:29:16 ( ID:qkyo0nicg8j )   [ Delete / Reply with quotation ]

Non, no, no, TMPGEnc can handle this perfekt. It's a trick to know how. There's no need to do a Framerate-Conversion. That's because you can handle this the same way, DVD-Producers do: PAL-Speedup.

If the AVI is a Film with 23.97 FpS, open it in TMPGEnc.
Choose PAL als Videoformat (25 FpS)
Select Advanced, select Do not Frame Rate Conversion
Encode the Video.

That's all.


ASHY  2002-12-19 00:15:53 ( ID:4adzcnohuc. )   [ Delete / Reply with quotation ]

Wrong, TMPG CANNOT handle this perfect. Selecting 'do not framerate conversion' will indeed produce a PAL movie with 4% speedup, but the audio WILL lose sync.

The movie will be speeded up to play at the faster 25 fps and will become shorter, but the audio length stays the same causing de-sync.

This can then only be remedied by shrinking the length of the audio to match the duration of the Video with Cooledit or similar.

The easiest way and produces pretty good results without the associated jerkyness is to use AVIsynth.
AVIsynth uses a method very similar to professional framerate conversion techniques.

B_Racer  2002-12-19 22:16:36 ( ID:f0tdjnbzg.2 )   [ Delete / Reply with quotation ]

Yeah, forgot this Audio-Thing. But i don't use AVISynth for that, because it speeds up the Audiopart too. That's why i'm using WAVELab to do an inverse Timestretch. That's much better, because the Sound sounds exaktly like the Original.



ASHY  2002-12-20 00:34:07 ( ID:n3gjkhi6dvc )   [ Delete / Reply with quotation ]

AVIsynth doesn't alter either the Audio or Video length when using the CONVERTFPS command, but uses other techniques to create a smooth conversion whilst keeping the movie the same length and thus the audio in sync.

Bug report - TE25 - TMPGEnc 2.59.47.155 No.32079
tha man  2002-12-18 15:25:33 ( ID:3hfvmug6ijm )   [ Delete / Reply with quotation ]

I just replaced the older version with this and thought this will be better.. :( but no.. When I set the video bitrate + audio bitrate it makes bigger files than older version with the same values (about 50Mb bigger). Even if I change the bitrate values it still makes same sized files... strange.. what causes this???

video audio
1140 160 48000 = 843Mb
1135 160 48000 = 843Mb (??? this is weird)

Anyone out there who also find this bug?

I have always used batch mode successfully. Recently, whenever i leave it on over night, i come back to find that TMPGEnc has closed and none of the movies have been encoded successfully. Any ideas?

thanks,
jonathan

Acts like some sort of buffer overflow that kills TMPGEnc, right? Was happening to me. I was also getting lots of "Read error at..." messages that would end the transcoding. Very annoying. What it was...

I installed an old, old, DVD authoring package. It installed its own ancient mpeg codecs, wiping-out the cyberlink ones from PowerDVD XP. PowerDVD worked, but TMPGEnc wouldn't for long.

I re-installed PowerDVD. TMPGEnc transcodes again! Life is good.

Question - TE25 - Exact definition of "Basic YCbCR not CCIR601" option No.32070
tearex  Home )  2002-12-18 11:32:01 ( ID:sm3bgpmfhmc )   [ Delete / Reply with quotation ]

Can somebody, if possible somebody who has access to the source code, give me the /exact/ definition of what the "Output as basic YCbCR, not CCIR601" option does in both of its states?

Especially, does it scale luma/chroma values, and if yes, in which of its states? Or does it only clip values when unchecked?

Thanks.

B_Racer  2002-12-18 23:33:20 ( ID:qkyo0nicg8j )   [ Delete / Reply with quotation ]

YCbCR uses a Luminance-Range from 0-255
CCIR601 uses 16-236

It has no effekt on the Chroma-Range.

Standard for DVD (and SVCD also) is CCIR. But you can (and should) use YCbCr if you are Transcoding a MPEG-Video.



ASHY  2002-12-18 23:46:26 ( ID:4adzcnohuc. )   [ Delete / Reply with quotation ]

This affects the range of values accepted for luminance and chrominance signals. YCrCb is raw samples, taking the range 0-255. In TV systems CCIR601 is normally used, which restricts the allowed range to 16-235 for luminance and 16-240 for chrominance signals. If you are mastering for TV (e.g. VCD, SVCD, DVD) then do not tick this option.

ASHY


tearex  Home )  2002-12-19 07:48:34 ( ID:sm3bgpmfhmc )   [ Delete / Reply with quotation ]

So which is true?

1.) Not ticking it throws away Y values below 16 or above 235, but leaves the others alone, and similarily for chroma?

2.) Not ticking it scales down the luma input values so that 0 becomes 16, 1 becomes ca. 17, etc. and 255 becomes 235, 254 becomes ca. 234 etc.

3.) Ticking it will make TMPGenc leave all the values alone.

4.) Ticking it will make TMPGenc scale up the values, so that 16 and below become 0, 17 becomes ca. 1, 235 and above becomes 255, 234 becomes ca. 254 etc.

Or is it none of those?



ASHY  2002-12-19 08:21:03 ( ID:n3gjkhi6dvc )   [ Delete / Reply with quotation ]

It depends on your input. If you are using DVD2AVI you have the option to output to TV or PC scale. TV will be 16-235 and PC 0-255.

If you are encoding for TV then the scale should always be 16-235 otherwise, and you can test this yourself, the picture becomes slightly darker, blacks become dark grey and whites aren't quite white, colours also seem to be become slightly deeper.

Your TV expects 16 to be the lowest value for black, use the 0-255 scale and 16 won't be quite black when outputted to you TV, but as I have said dark grey the same is true for white.

If you don't tick then all values will be correct for TV.

I suppose the choice may partly be down to personal preference, but if you want my advice and the correct scale for TV then you should be using CCIR601 for all your encodes.

ASHY


B_Racer  2002-12-19 22:26:04 ( ID:f0tdjnbzg.2 )   [ Delete / Reply with quotation ]

ASHY is nearly right. But DVD2AVI is a little Buggy.
You have two Options to Choice:

PC- or TV-Scale
YUV 4:2:2 or RGB

The different Combination of those two gives completely different Outputs.
RGB + TV-Scale gives a darker Picture. So it depent's on the Settings, if CCIR or YCbCr is right.

If you are not shure, how to handle this, use always CCIR. Better to dark then to bright (and Off Standard).




Question - TE25 - Quicktime plugin required No.32068
Paul Clarke  2002-12-18 11:13:33 ( ID:maa/fgxat5f )   [ Delete / Reply with quotation ]

I need to convert some quicktime MOV files to mpeg format. I have found some references on forums stating that there is a TMPGenc plugin for Quicktime that allows TMPGenc to convert MOV files to mpeg.

Can you please advise
1. if this is correct?
2. The name of the plugin?
3. where to get the plugin?

Thank you


minion  2002-12-18 22:19:53 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

You can get the Quicktime Mov Plugin in the download section of "www.vcdhelp.com"...you can easily find it elsewere if you look on a Search engine.........

I want to edit, split and rejoin 1 file. How can I stop TMPGEnc from creating overlap.

Thanks

I don"t Understand what you mean, If you edit it correctly then there shouldn"t be any Overlap....

Hi,
When i was converting an AVI file to MPEG-1 I got this error message at 69%
what would be wrong? Please help!!!!


minion  2002-12-18 08:46:39 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

This error Is Cause By Bad Or Corrupted AVI files..Usually with Files downloaded Off the net..There is no real Fix for this accept you can start encodeing were it crashed useing the Source Range and Join the 2 parts together with the Merge & Cut....Or you might try Frame serveing the file to tmpgenc ..



Question - TE25 - QuickTime Authoring No.32057
Russell  2002-12-18 01:58:20 ( ID:2jy5nw6ruw6 )   [ Delete / Reply with quotation ]

I have been trying to encode an mpg file to mpg1. WHen I tried it the first time I got a message saying that TMPGEnc needed to download QuickTime Authoring. Every time it tried it said it was corrupted, try again.

It's always corrupted is there anywhere I can manually download it from and what is the file called.

If I try to encode the file without the download TMPGEnc either stops responding or produces a file with no sound.

Help!

Russell


minion  2002-12-18 08:43:12 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

This is wierd..You do not need Quicktime to to encode Mpeg to Mpeg But you do need it to encode "Quicktime MOV" to mpeg...So Maybe the file you are trying to encode isn"t a Mpeg file but a Mov file???? since This problem is so wierd I don"t really have a Solution for you....


Russell  2002-12-18 16:43:56 ( ID:5zel0mlh.0a )   [ Delete / Reply with quotation ]

Thanks

I think it's something to do with the sound encoding. TMPGEnc says it isn't a valid audio stream if I try to demux it.

I have the Quicktime plugin and can convert .MOV files (though without sound, hmmm) so I assume the authoring is a different plugin or whatever.

Strange thing is Winamp 3 will play the original but the sound turns into a loud hiss after the first couple of seconds but MS Media Player plays it OK.

Russell


minion  2002-12-18 22:15:16 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

Well you Can extract the audio to a WAV file, if it is a Mov file then you can use "Sound Forge" to do this , then you can encode the Wav file as the Audio source...



Question - TE25 - SVCD frame skips ??? No.32055
linda  2002-12-18 01:14:21 ( ID:f8b7qd.dvdg )   [ Delete / Reply with quotation ]

After converting a DVD to SVCD (using the SVCD Movie Template) and then burning it to a CD-R, the movie play well if it wasn't for occasional frame skips. It's if the movie is fast fowarding by a second or two from time to time.
Can anyone help me solve this problem ???
Thank You.


minion  2002-12-18 08:40:11 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

Do mean that the Video seems to Speed up or slow down Just for a second once in a While??I believe that this is Caused By sudden Bitrate spikes in the encoded Video wich Makes the Drive in the DVD Player have to suddenly speed up But the drive can"t speed up fast enough..This is a Dual Problem, a Problem with Tmpgenc Haveing Bitrate spikes and a Problem with the Drive in your DVD Player Not being fast enough to compensate for the Bitrate spikes...I don"t really know of a Solution for this accept Maybe useing a Lower Bitrate or a Encoder that doesn"t spike the Bitrate, or get a DVD Player with a Faster Drive in it....



Question - TE25 - Grayed out Settings No.32053
George  2002-12-18 00:04:30 ( ID:utnbm3gfifa )   [ Delete / Reply with quotation ]

After selecting the file to convert to MPEG1 and the Wizard opens, I have ot way of changing the settings such as FPS, SIF, or Kbit/sec, when clicking on settings all of these options are grayed out and won't let me change them. Any help?


minion  2002-12-18 00:30:33 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

To Change the settings you either have to load the "Unlock.MCF" template from the "Extra" Folder or Click on the name of the setting it"s self then go to "Unlock",Remember you Have to encode the mpeg file to the same Frame rate as the AVI file, and you have to keep the Resolution to the standard for the format you are encodeing to, meaning if the AVI file has a Frame rate of 23.9fps you have to encode it to 23.9fps and if you are makeing a VCD then the resolution has to be 352+240 for NTSC VCD..you can"t encode for example a 25fps file to say 29.9fps ECT....
