HDV capture,timeline,broadcast information please

[Thomas Morter-laing]

Hi,
So I hope I can help:
When capturing the footage, capture it to Apple Prores 422. Amongst many reasons for this is because it renders faster because it is more efficient with the processors, and is sort of less “lossy” than other codecs. It also has a 422 colour space for any colour corrects or quick grades you may be doing.
After that I would set the sequence settings to the same- Apple Prores 422 as your compressor (or “renderer”). You don’t need Prores 422 because it wont help and will just add massive file sizes, because you’re only using and HDV camera.
For exporting, for the web I would use H.264 because it is both highly compatible with most modern computers, and also keeps very good (HD) quality at very low file sizes. Use the ‘youtube’ preset in Compressor for some good results.

As for the output to TV, thats a little different. They should have supplied you with a sheet saying exactly what they want. HDV is not acceptable for a lot of “True” HD channels, because of the bit rate it records at and a few other things, but you would have to talk that through with whichever TV channel is online-ing and broadcasting it because they all have different requirements.

With DVD- its near impossible to keep it HD. You can fit small HD FILES onto a DVD, but then it wont be a proper DVD, simply a data DVD with the files on it (wont play in DVD players). You can trick programmes like Toast into burning short pieces to a higher frame size, to get an “HD DVD’ on a “normal DVD” but this can be, and is often, very problematical (DVD players cant keep up etc). Again, I would recommend using the ‘DVD Best Quality” presets in Compressor to export, then use DVD Studio Pro to burn the actual DVD. They wont be DVD, but they’ll look very good.

Hope some of that was helpful.

Hi

Thanks for the inforamtion very helpful, but if l can add. once l have completed my edit and finalise the edit and export to quicktime file for the next steps, compressor etc.

l capture and edit in Pro res 422HQ 10bit, finalize edit, can it be exported as a dvcpro HD file to be broadcast on a HD channel that uses DVCPro HD work flows?

if l use H.264 for web, whats the average file size to keep it good for broadcast using Streambox as my portal (if you know that software)and if l use compressor you-tube is there better settings to use than this?

I have one question relating to DV if you may know please?

l shot at times in DV in the field and edit in the field. time-line and capture are dv pal, export to quick time once edit finished whats the best compression rates to use for FTP file transmitting using streambox. Al the FTP transfers are for broadcast in International News?

we have some presets that we use but quality could be better for transmission if you have any ideas and help l am listing

thanks again for all your help appreciate it

“l capture and edit in Pro res 422HQ 10bit, finalize edit, can it be exported as a dvcpro HD file to be broadcast on a HD channel that uses DVCPro HD work flows?”
-Well yes, but why on earth capture and edit in 422HQ 10bit??? You shot on HDV, NOTHING you do with make it ‘true’ hd or better quality. HDV is an 8bit codec- by using the above workflow you are only wasting time, effort and dis space. I guess to export it using that specific codec you could still use compressor, just click on the settings button of a preset, or make your own, and set the codec etc.

“if l use H.264 for web, whats the average file size to keep it good for broadcast using Streambox as my portal (if you know that software) and if l use compressor you-tube is there better settings to use than this?”
-Depends on the length of the video etc. You need to give more info I think here, but it will be absolutely fine for the web if you use that preset.

“I have one question relating to DV if you may know please?”
-Sorry your question here was a little confusing to me, it depends on a lot of factors and to be honest Im not sure what streambox is… hopefully someone else can help here…

“we have some presets that we use but quality could be better for transmission if you have any ideas and help l am listing”
_ what are the presets, where is it broadcast, what’s the delivery format etc. ?

One suggestion: don’t use ProRes HQ. HQ only improves quality for 2K and above. At standard 1080 HD and below, all HQ does it increase file size and bandwidth requirements with no useful increase in quality. Capture to standard ProRes 422 and your 1080 footage will look beautiful.

Thanks again for the info very helpful makes a little more sense

Pro res standard it is but whats the Pro Res LT for and do you know the bit rate?? not sure what its used for

last thing re the export if l am editing in Pro Res when l finish and finalize the edit what should l export it as ( this is for file keeps and master and also for Pre Compressor and DVD formatting and Web

as to the what are the presets, where is it broadcast, what’s the delivery format etc. ? question

its for broadcast in the USA we upload via transmit export quick time to MP4 the presets l don’t have with me now, but l think the highest preset was 256 file size and length of stories are around 130 to 2 minutes that’s for the H.264 question

all shot in DV Pal

thanks again guys

“One suggestion: don’t use ProRes HQ. HQ only improves quality for 2K and above.”

not quite right… HQ uses the 709 colour space instead of 601 – imperative for HD broadcast requirements.

[jon smitherton] “not quite right… HQ uses the 709 colour space instead of 601 – imperative for HD broadcast requirements.”

Jon,

the color space in prores is defined by the source and is variable with the input format.

SD footage is handled as REC601, HD is rendered as REC 709.

So Prores non – HQ is in the 709 colour space if say, editing in a timeline where the source is from HDV? Does this mean the only advantage of HQ is quality over 10 re-renders? (as per the white paper)

Be good to know this with regards to space – disk-wise.

Thanks Jon.

Sorry for the dumb question but it just occurred to me, when you talk of re-rendering, you don’t meant literally when the red bar appears and you render that do you? As in, I’m fully aware of generation degradation but that doesnt happen just by needs rendering does it?
