m2v incompatible format in DVDSP
Hi! In desperate need of some advice:
I have been exporting a sequence from FCP to Compressor where i’ve used mpeg 2 Elementary stream and a seperate audio compression AIFF 48:16.
Audio is all good, but DVDSP will not accept the m2v file, saying ‘Incompatible Format’
If these are my sequence settings :
Frame size: CCIR 601/DVPAL (5:4)
pixel aspect ratio 720:576 PAL CCIR 601
Editing timebase: 25and here’s the elementary stream mpeg2:
Description: MPEG-2 Elementary Stream, 15 Mbps.
File Extension: m2v
Estimated file size: 6.59 GB/hour of source
Type: MPEG-2 video elementary stream
Usage:generic
Video Encoder
Format: M2V
Width and Height: Automatic
Pixel aspect ratio: Default
Crop: None
Padding: None
Frame rate: (100% of source)
Frame Controls: Automatically selected: Off
Start timecode from source
Aspect ratio: Automatic
Selected 16:9
Field dominance: Automatic
Average data rate: 15 (Mbps)
2 Pass VBR enabled
Maximum data rate: 20 (Mbps)
High quality
Best motion estimation
Closed GOP Size: 1/2 second, Structure: IBBPwhat does the (5:4) on the sequence’s frame size mean?
I am still quiet new to all this so forgive my ignorance,its about 11minutes long w 2 audio outputs…
Any help would be amazing, thank you -

“If you don’t know what you’re doing please start with a preset. Apparently you don’t know what data rate DVD Video can handle. You can not “turn up the volume up to 11” you must stay within DVD spec.

Like Craig said, your data rate is too high. DVDs can handle a max of 9.80 Mbit/s total for the audio and video content on the disc. I’ve had issues with DVDSP not accepting .m2vs that were even within this spec.
You obviously want to be able to have the highest quality video possible, but you also don’t want to deal with cheaper players not being able to play a disc. I’m not sure how much of an issue this is anymore, but I’ve heard of people having problems.
So, short answer use a preset, aka lower the data rate.

Some will keep peaks to 7.7mbps, others 7.2mbps. I’ve had peaks as low as 6.5mbps (and CBR will work for shorter encodes) because I’ve seen some very finicky older players.

Thank you Andrew,
I obviously got all the data advice a bit mixed up and didn’t even look twice at the elementary stream preset! Running short of time I took your advice and opted for the easy option and less quality, and it all worked out well. Relief!
