Workflow for HDV to SD delivery
I will be editing a program in Cs5.5 on a PC. Footage supplied is in PAL HDV formats that is upper field m2t and mpeg from a Sony HDV camera and Canon DSLR respectively.There is also – progressive mp4 footage from three gopros. Delivery format is SD. Very concerned about clip jitter on air. What would be the best workflow to employ and deliver to SD without going the DV format route. I do have a decklink HD card but it is a legacy card which does not fully work on 64bit machines – I can export to Black Magic uncompressed but the broadcaster would not be able to import the file without loading the codec which they will not do. Broadcaster is dominated by AVID systems. Advice much appreciated.

Sony = PAL HDV @ 50i
Canon = PAL @ 25p
GoPros = PAL @ 25pAll sound about right?
Because going from HD to SD isn’t an even conversion, you’ll need to deinterlace the 50i footage before resizing to SD.
I would simply use an HD timeline at 25p, deinterlace the Sony footage and then downconvert to standard definition on export, and let that conversion handle the re-interlacing.
I don’t understand what you mean when you say you want to avoid DV. Is the broadcaster looking for delivery on DV tape and you don’t want to use a DV tape deck?
You’ll need to adhere to the delivery specifications of the broadcaster/network. If you know they run on Avid, offer to deliver with an Avid encoded file, you can get the codecs here and they are compatible with Premiere when exporting to MOV https://avid.force.com/pkb/articles/en_US/Compatibility/en372311

Many Thanks for that – I need to deliver in file format so I did not want to lose the 4:2:2 information.

Second question can I edit with the gopro footage and deinterlace in premiere timeline or should I convert footage beforehand?

Think that was a dumb question:)

GoPro footage is h.264 and, for all intents and purposes, should perform in a similar manner to DSLR footage.
In terms of deinterlacing, once you have your segments cut, right click them in the timeline and select Field Order… and you can select “Always deinterlace”
Premiere discards one field of each interlaced frame, and then fills in the gap. You’ll lose a little quality in terms of horizontal resolution, but you’re also downconverting to SD, so I don’t think you’ll really notice any real hit to quality by the time you complete processing.
Alternately, you can deinterlace in After Effects with some more robust plugins like Fieldskit or Magic Bullet Frames. Some PC users also use something like AviSynth or VirtualDub to process deinterlacing as an intermediate step. Just food for thought, but I don’t think you have to follow this more advanced path for your situation.

Thank you for that clarity:)
