Compressing M4v for DVD Studio Pro
on Nov 7, 2010 at 1:29:34 am

Ok, so, I really need some help here, I hope some one out there has a solution. I would greatly appreciate it.

This is a multi-question post.

I have two 4-hour DVDs that I need to subtitle. I ripped them with Handbrake.
The result were m4v files. Since the subtitling is a lot, I am using MovCaptioner to generate a subtitle file and integrate everything in DVD Studio Pro. The problem is m4v files playback is fine when i play them using quicktime player, but when I import the m4v files into DVD Studio Pro, It is imported without sound. I have everything in final cut pro since making the firs transcription was easier using that than the quicktime player. Rendering from FCP leaves me with GBs and GBs per video plus its a hassle regarding the frame properties and ratios... and almos al the clips ripped are different sizes and codecs vary. I have no idea who or why they were made like this.

I need to know into WHAT to transcode my m4v files to put them back into DVD Studio Pro so the image is not so deteriorated.

Rendering subtitled movs from MovCaptioner is slow (did i mention its urgent?) and it looks really bad.
Transcoding with compressor has not improved too much and i get huge files if i transcode using proress422. If i use DV NTSC i get horrible picture plus its also more than 2 gigs per file. A ripped m4v that is about 390 MBs can go up to 3 GB.

MPEGStreamclip has been as of yet my best option but still: I have huge mov files that dont look as the DVD (not that is looked great in the first place, but a decrease in quality is quite noticeable.)

Also I need to keep it the same amount of DVDs, so I can't stick 14 quicktime movs each ranging between 3 and 7 GBs. per disc.

Hope this wasn't too redundant.

Thanks!

Unfortunately that's the way it is with ripped material. If you don't have access to the original footage, that's what you have to live with.

I guess so...

Using MPEGStreamclip I have tried ripping the disc to MPEG and MPEG-2 and it looks great. Except when I try to import it as an asset into DVD Studio Pro, it prompts me with "incompatible format". Any ideas on that?

thanks

Ivan,
first of all - using m4v for DVD (even as a temp-codec) is a very bad idea. m4v is MPEG4, a very high compressed codec - that´s a distribution-codec but no Editing-Codec.

if you´re using streamclip you could simply demux the original VOBs into the elementary streams to use them with DVDSP and create a new DVD out of it. but as far as I understand you need to re-encode at a lower bitrate because you need to put more films on the disk as there has been before.

so the best way to go is to create a quicktime-mov from the films (using streamclip export (cmd-e) and create a PRO RES file.

take care of the field-dominance, you should check it with streamclip prior export looking into the VOB-files information (cmd-i).

to do a proper encoding of your new assets you can use compressor.

cheers

Yes, finally I just ended demuxing with Streamclip and it looks just fine on tv. And by "just fine" I mean it looks just as good as the original discs I was handed. Looks very compressed, but ok for what the client needs.

The issue with transcoding to prores was that it gave me huge files and I need to cram 8 hours into two SD DVD. Since these are DVD sets they take on trips and training sessions, they don't want to be traveling with sets of 7 or 8 discs, they want 2 at the most.

Any suggestions for subtitling software? MovCaptioner seems unstable. Has anyone had experience with Subbits?


thanks!

A bit off topic but since you've been tons of help, and this sillt relates to DVD Studio Pro, here goes:

I used textwrangler to make a txt file line by line, it was pretty quick. Imported that to MovCaptioner and from there exported STL files. Pretty quick also. Imported that to DVD Studio Pro and fine tuned timing there. Not so quick but ok.

Trouble starts here: I have 5 videos on this disc. Subtitles in 2 of them. For one of the videos I had to import the subtitles twice, in 2 different subtitle tracks and was drag-and-dropping from subtitle track 2 over to subtitle track 1. Then DVD Studio Pro crashed and now the project won't open.

If I go file/open/ the the application starts reading the project but freezes for ever. If I double click the DVD Studio Pro project, it crashes a bit after the DVD Studio Pro splash screen.

Is there any cache file or plist file I could delete in order to be able to open my projet or do I have to make it again?

Thanks in advance,

Nine times out of ten you have to make it again- unfortunately... Once a DVDSP file gets corrupted it's corrupted for good.
