The Blu-ray specification allows for authoring mixed media discs. Mixing PAL material on a NTSC disc is allowed and works in Adobe Encore.
In TAW6 i can mix 720p50, 1080i25 and 1080p24 without issues/re-encodings. But, if i create a new project and try to mix 1080i25 and 1080i30 TAW6 will force a re-encode of one of the two files depending on the mode you choosed when you created the project.
If i create a PAL project and import 1080i25 and 1080i30, TAW6 will re-encode the 1080i30 material to 1080i25. If i create a NTSC project and import 1080i25 and 1080i30, TAW6 will re-encode the 1080i25 material to 1080i30.
There are two problems here:
1. The Blu-ray specification do allow 1080i25 and 1080i30 to be authored on the same disc.
2. Converting framerates simply don´t look good, so this bug must be fixed.
The source footage is created by Premiere Pro CC2019 using the TMPGEnc Premiere Pro Plug-in. I can mix the same 1080i25 and 1080i30 footage in Adobe Encore.
I believe the Blu-Ray spec does NOT allow mixed formats within the same TITLE - hence why one of the files is re-encoded and isn't a problem with the software.
To get around this, simply create a second TITLE and add the second file to it. As long as all the files in each title have the same format and resolution, normally no re-encoding will be needed (unless none of the files match the Blu-Ray standard!)
I've done this several times when you want to add a mixed set of files to the same Blu-Ray or DVD. Create as many titles as you need (up to a maximum of 99 on a DVD and, I think, 199 for a Blu-Ray). Creating the menus for multi-title discs is slightly different to adding everything to the same title, but is easy to figure out.
Roger, I should have read your question more closely. It's also difficult to establish what exactly is contained in the Blu-Ray standards!
For HD video, PAL or NTSC should theoretically be irrelevant because of course HD doesn't use either. Because of this I've often wondered why, in TAW, you have to select PAL or NTSC for a blu-ray project, other than if you're adding standard definition content that actually is encoded in PAL or NTSC form. I presume this is a hang over from creating DVD projects, which, as you say, can only be one or the other.
I still don't think you can mix video of different standards, resolution, or framerate etc in the same track without some of the files needing re-encoding. If Blu-Ray supports both PAL and NTSC on the same disc, my guess is this should be allowable at the Track level, but not mixed standards within the same track? (OK, previously I said "Title" - more correctly I should have said "Track").
I am using a separate clips for each Track in TAW. I never add more than one (1) clip to a Track in TAW. Mixing PAL/NTSC footage in one Track would naturally cause issues/re-encodes. The odd thing is that some PAL/NTSC are ok to mix in TAW6 as i wrote in my first post so to me it indicates that it is a bug since some combinations of PAL and NTSC footage in separate Tracks are O.k though the BD standard can be mixed, be it HD and/or SD.
I tried to trick TAW6 by replacing clips in the BDMV\STREAM folder but that don´t work as expected. If i create a PAL project with two Tracks, one Track with PAL clip and one Track with NTSC clip the NTSC clip will be re-encoded to PAL. If i then do a new NTSC project with the NTSC clip and then swap clips in the BDMV\STREAM so i have one PAL clip and one NTSC clip in that folder there is some metadata that force the Blu-ray player to playback the NTSC clip as some kind of PAL. The player report that the NTSC clip is PAL as well.
If i create a BD-disc in Adobe Encore with the same PAL and NTSC clip my Blu-ray player will report correctly, iow PAL for PAL and NTSC for NTSC.
I hope this will be corrected in a future update of TAW. :)
hi im trying to capture video clips from a panasonic hdc-hs25 hd cam with my tmpgenc5 sw but it's not letting me capture more than 200 clips. anyone know if newer version (6) of sw can do this? or how i can do this with tmpgenc 5?
I think 200 is the limit for version 6 as well.
If you can combine them into one video, that could work. In other words, import 200, output as one video, then create a new project with the rest of the clips and the combined clip.
Whenever I try to do a Constant Bitrate encode using the Intel QuickSync it always gets to 16/X frames and sits there while the total completion time keeps climbing. For example, my encode has been sitting for 20 minutes at 16/163840 frames and is showing a completion time of 1380:42:00 and climbing.
It does this for every CBR encode that I try regardless of the original source video size/length.
When I choose Shutdown as finishing task, it seems the system goes idle instead of shutting down. (this is Windows 10 / 1803)
The only visible track left by this action is in the Windows System log:
Log Name: System
Date: 18/03/2019 23:46:51
Event ID: 1074
Task Category: None
The process TMPGEncVMW6.exe has initiated the power off of computer XXXX on behalf of user XXXX\Benoit for the following reason: Other (Unplanned)
Reason Code: 0x0
Shutdown Type: power off
the next event in the System log is only 8 seconds later and is an information-level event from 'Time service', but also in the Application log an event 102 from ESENT where 'The database engine (10.00.17134.0000) is starting a new instance (0)'.
This would suggest a reboot instead of a shutdown....although I see no clear event related to a reboot (e.g. events from the kernel; and 8 seconds seems a bit short for a reboot anyway)
Is there a way to check whether I need to enable the option to allocate higher bitrate for DVD subtiles, without carefully watching the whole film with subtitles turned on ?
Feature film is pretty long, has already been carefully encoded and hence I would like to avoid re-encoding with a lower bitrate for the video, to allow higher bitrate for subtitles.
In case of insufficient bandwith for subtitles, will dropped subtitles occur with software players as well as with home DVD players ?
When I'm in 'cut' of video file, I suffer from long time to load thumbnails in seek section. When I jump into some point in video, it takes 5-15 seconds for thumbnails to appear. That siginficantly slows down work. Changing time of thumbnails distance doesn't accect. Once I scrolled through video, thumbnails are generated and it's fast. So I would even like to have them generated it production tool or so, so when I start working with clip I already have them.
Are there some factors to change, to make that faster? I have to seek a lot through long file it really affects me.
I see that during seeking, while thumbnails are generated, CPU is loaded signigicantly, 4 cores at 40-50%. Once thumbnails are generated, CPU load goes down. I tried to use GPU/Intel video decoding, but it didn't change anything.
I created RAID0 array from SSDs, to have huge read/write time but it didn't help.
Interesting is that when I jump into somewhere in the file, in preview section I immediately get image, so I assume this can be done almost 'online'. The same I would like to have in thumbnails.
I tried this wit several different input sources and it's the same.
