to make things easier at con everything is authored as a dvd and if a video is at a different frame rate, all the videos after that video on the disk are thrown out of sync.

Ask Vlad about 2005

I can easily change the frame rate, but it just adds time and an additional step to the process as the best way I have found to do that is load the video into premiere in a project set at 29.97 and re-export it.

That'll leave most AMVs (which would natively be 23.976 because that's what the anime is) with a choppy look from the frame rate change...the best thing to do is encode it to MPEG-2 480i (if the con is not going to play the videos in HD).

What am I missing?

wiki wrote:ATSC also supports PAL frame rates and resolutions which are defined in ATSC A/63 standard.

It's JUST technicalities, most devices and TVs will accept frame rates on either standard ATSC A/53 or ATSC A/63. Of course ATSC Standard A/72 covers the frame rates of both...

But NTSC (the one stated in the rules) covers neither for 720p video - that was the only point I was making - the person asking the question had a valid reason to do so because it wasn't addressed in the rules.

Dinger, next time just specify MPEG2 720x480@29.97fps... no 720p, no wmv, no avi... just straight up MPEG2. Less work on your end and no confusion.

would love to specify only mpeg2 but cant merge 2 mpeg2s un;less they have the same settings, so I do put that extra work in, I should have just dropped the NTSC from the line in the rules

Yeah, I think they need to think out all the technical details before posting the rules next time maybe...

So, I have a pair of 720p 23.976fps MP4s to submit. Should I just ConvertFPS(29.97) them and re-encode?

So are you going to convert all the videos to MPEG-2 yourself?

Well, considering they play in the AMV room on Sunday (all entires), I've not had any issues with then in any of the past years so far

Yes, each entry gets encoded with virtualdubmod into uncompressed avi, and then encoded into mpeg2 with the same settings. and at each step in the process I watch it to make sure its still playing correctly. This removes any variables between videos

If that is the case then frame rate shouldn't be an issue, as videos with 23.976fps videos can be encoded with 3:2 pulldown and 29.97fps content can be encoded progressive and both would play back fine on the same disc (even if joined). With that in mind though, you might want to tell people NOT to encode it interlaced, because if they choose the wrong field order when they encode it to 29.97fps interlaced, it'll really screw up the re-encode and playback.

I was going to suggest the same thing.

I may or may not have an action entry this year, depending on a.) how motivated I'm feeling after cranking out 2 videos in the last month, and b.) how badly I get sucked into Dragon Age 2 next week. :awesome:

Oh, and of course getting everything ready for being one of Vlad's trusty assistants, of course. Assuming he doesn't send me any more con program write-ups. :shock:

Maybe you need to *cough cough* take some time off write-ups and do Iron Editor :P We still need a challenger or else California wins by default :shock:
