B Sharp Posted January 12, 2016 Report Share Posted January 12, 2016 Hey everyone. I am trying to use zaxconvert to convert a file from 23.98 to 29.97. When I open zaxconvert, I only see the option to "pull up" or "pull down". I am not quite sure how to takle the conversion from 23.98 to 29.97. Any help is greatly appreciated. Thanks in advance!

RadoStefanov Posted January 12, 2016 Report Share Posted January 12, 2016 Convert normal then change metadata with waveagent. Works great Quote Link to comment Share on other sites More sharing options...

cmgoodin Posted January 12, 2016 Report Share Posted January 12, 2016 49 minutes ago, RadoStefanov said: Convert normal then change metadata with waveagent. Works great That would only work as long as the files all start on an even second. SD always starts files on an even second. Earlier Zaxcom files I believe started at whenever fractional second the record button was hit. Maybe the new machines start on the even second but it would depend on what version of Deva or other machine the files were recorded on, so make sure the start time code at 23.976 all start on even seconds in the files you want to convert before attempting to convert them to 29.97 in Wave Agent. Perhaps this is already handled by the current version of Zax Convert so it may not be a problem. Quote Link to comment Share on other sites More sharing options...

Can you please explain which options to select if I am changing my file from 23.98 to 29.97? Everyone says that zaxconvert can do this, but nobody can tell me how...

Derek H Posted January 13, 2016 Report Share Posted January 13, 2016 Zaxconvert cannot do it. Wave agent, a different utility program made by sound devices can. As far as I know Zaxcom recorders still start whenever you push record not on necessarily on the 00 frame. Quote Link to comment Share on other sites More sharing options...
syncsound Posted January 17, 2016 Report Share Posted January 17, 2016 Has post actually tried to sync the files yet? Since they're both non-integer frame rates, it might work. Quote Link to comment Share on other sites More sharing options...

Perhaps this is already handled by the current version of Zax Convert so it may not be a problem. I don't think it matters. The Start TC value is stored in both the bEXT and iXML chunks in the BWAV file as a "Samples Since Midnight" value, not as a HH:MM:SS:FF timecode value. So the Start TC value would be the same whether the frame rate was 23.976 or 29.97. The frame rate is stored in the bEXT as the ‘SPEED’ parameter and in iXML as the ‘TIMECODE_RATE’ parameter. DAWs and NLEs can then convert the "Samples Since Midnight" value to the appropriate HH:MM:SS:FF timecode value (and visa versa) depending on the FPS. So theoretically, there shouldn't be any issues since our recorders don't actually do anything in frames, except create metadata stamps. On 1/12/2016 at 9:56 PM, B Sharp said: Hey everyone.

As others have voiced, you'll have to use Wave Agent to change the frame rate metadata on those files, as ZaxConvert cannot do that. Alternatively, you should be able to just drop those same files against a 29.97NDF timeline. Video at 29.97NDF will sync with audio at 23.976, with timecode matching exactly at the at the top of every second (:00 frame mark). Quote Link to comment Share on other sites More sharing options...
