Seem to be working nicely Luke. I’ll give the MJPEG a go…

Cheers,

Very nice work on your codec. It works very well and it is very fast!

Do you plan to add a data rate to reduce file size if we want to do offline and non-broadcast?

Best regards

Still waiting to load this up and try. But meanwhile, what kind of RT performance are people seeing with M-JPEG?

And as an aside, M-JPEG imports and exports really fast on Avid systems too. Not as fast as Avid codec files, but next best.

I was trying today to capture from VHS. This was not so good info tape supplied from my customer. No luck. Crackling sound, and lots of losing sync. When I conected my VHS to Monitor all was OK. Is anybody try this with previous drivers? YUV from Betacam to MJPEG is OK. Very fast rendering from uncompressed timeline to MJPEG and quality is exellent. Good work.

For the fun of it I tried playing back a mjpeg 1280x720x23.98p on my old internet computer which is a P4 2.4GHZ with 512 MB of ram. It played back in realtime with no problem at all. Very nice! I also converted a DVCPROHD file to mjpeg and did a difference blend in After Effects to check how different they were and they were very very close. Very nice job!

Hello,

It solved my audio clciking problem I had in Adobe Premeire Pro 2.0. I will check the On-line Jpeg codec tomorrow. DOes anyone know if you can make the MJPEG compression variable to do off-line workflow?

Also if capturing raw camera Component from a HDV camera would quality be as good capturing to MJPEG in comprassion to Uncompressed 4:2:2 HD codec? I know the MJPEG will have slight compression but would this be viable?

Thanks,

Leo

Hi Oscar,

Yes, we should probably be able to add variable data rate but first we just want to see how the codec is going before making any changes. Thanks for letting us know it’s going well at the moment 🙂

Leo:

I missed (and can’t find) your post on audio clicking in PPro 2. What was the nature of clicking and how did you resolve it? A sound engineer recently heard (which I never have) clicking in my audio that was captured into PPro 2.

Does your VHS deck have a built-in time-base corrector? Capture cards need a stable signal, and that requires a TBC. Betacam decks have built-in TBCs. You might be able to route the VHS out through the Betacam deck and capture that way.

Hello Bill,

I was having audio click on a Blackmagic Design project where I imported non Blackmagic codec video files, such as AVI Captured to AVI with Adobe Preemire Pro 2.0 using a DV PAL setting. Quicktimes and AVI supplied on drives or disc from other edit suites in DV PAL 4-3 as well.

I had problem only on the monitoring. Let me explain.

1. Made a Blackmagic Design Project Uncompressed SD 422, DV PAl

2. Imported Quicktime, AVI Microsoft DV codec.

3. Added the clips to the timeline, getting audio clicking. If I then disabled the video track then the audio would playback perfect. As soon as the video track was enabled again then any audio on the timeline with video or a title or anything playing along side audio on the timeline produced this clicking audio.

4. if I then rendered my Quicktime, Microsoft DV clips to Blackmagic codecs then the problem worked fine.

When I installed the new Multibridge Extreme Drivers lastnight it asked me to update my firmware then installed drivers and launched Premeire pro 2.0 and the Blackmagic project with the non Blackmagic codec files using AVI Microsoft dv files played back with my video track enabled with audio and I had no clicking sound.

I hope this helps? My system specs are on my profile on here.

Thanks,

Leo
