  • AVCHD2HQ converter - strange flashes?

    Hi to all!

    I am using Edius 4.6 with a Intel Quad CPU Q6600 @ 2.40GHz and 2 RAM GB. I just got some footage recorded in HD with a SONY HDR-SR12 in AVCHD. I didn't think that would be a problem because I also have AVCHD2HQ converter instaled on my workstation, but the conversion results are terrible: no matter what settings I choose in HQ Codec Setup, I always get image "flashes" on my clips, especially on sunny outdoors and when the camera is moving less!

    Has anyone else experienced this kind of problem with AVCHD2HQ converter? It simply doesn't work? Is there something I'm doing wrong? Is it the camera?

    The only eficient alternative I found is to export the clips from inside Edius to AVI, but that takes too long, since I am working on breaking news! The news website I work for is considering purchaising a SONY HDR-SR12, because, in theory, we would spend no more money on miniDv tapes and it was suposed to be much more eficient and fast than the miniDv workflow... but... aparently it doesn't work?

    I really need some help here, so I really apreciate some insight about what is going on...

    Absolutely the same for me with SR12 and quad core QX9650

      Edius is just not there for AVCHD yet. With no conversion, raw AVCHD files captured with Sony Motion Browser software from the camera you can work straight on the timeline with Vegas 8 even with my old AMD 4200X2. Rendering is slow for me ( but still faster than Edius ) but you should be fine with your new Quad core. I just used Edius 4.6 to edit a multicam , 2 FX1 HDV and my SR11 AVCHD raw files on the timeline( used DV from my HC96 and then cut SR11 file to match afterwards to improve editing flow). IT took a while to render to HDV output ( 2 hour 15 min timeline took about 7hours to render. Shorter than the time it would have taken me to convert all the files to HQ!!!!!).
      For your application at the moment I would use Vegas 8 and use the raw files. You could then write your backups to BluRay directly too.

        it is imho the AVCHD2HQ Converter.... same "flashes" or "color pumping" issue

        a) equal from my SR11 from stick without the PMB ... or over import per PMB
        b) other serious User in the german speech area the same with SR11 or SR12 files
        c) funny but true (and self tested) same files nativ on 4.6 timeline >> projectsettings 1920x1080 >> export to HQ = no problem

        d) not all attempts from the same file to encoding with the "AVCHD2HQ Converter" produced the same "unusable" result

        We have no info on the download website, no info in the ReadMe, no info on the forum from official GV person in charge,
        AVCHD2HQ works with files from company xxx, and it works not reliably with files from company yyy

        export (render) time to HQ fine is in my (small) case ~ 2,5 x RT .......same time as with the AVCHD2HQ

            All I know:

            - There are issues with 24p AVCHD content conversion (Canopus HQ codec issue)
            - Panasonic material exhibited problems with the actual conversion, but these are resoved in v2.00 of the converter

            Beyond that, I have no further information.

            This is the last time I will say this: Vegas Performance vs EDIUS Performance.

            Vegas DOES NOT DO FULL FRAME RATE/SIZE PREVIEW during AVCHD playout (it downsamples and can drop frames). This gets you realtime playback that appears smooth.

            EDIUS MUST do full frame rate/size preview during playout. This is no different to any other format used in EDIUS. The ONLY exceptions are XDCAM (which can use proxy data), and Infinity JPEG 2000 (bitlayering modes).

            Currently, I don't know if there are any plans to change this philosophy with EDIUS (since it's a major selling point, after all). This is why we made the AVCHD converter.

            As far as multithread performance goes, it's entirely possible that the optimisation isn't yet fully realised. That's typically an ongoing thing. But we are not pulling the proverbial wool over anyone's eyes when we say we support AVCHD - technically, we do.

              I would not argue about the meaning of the word "technically". Just'd like to ask you - are there plans to add multi thread support for AVCHD*in the future Edius updates?

                I have no info - things like that tend to come around of their own accord. The last I read, there was some AVCHD related things planned for the next major release, but as with anything concerning future upgrades, things can change.
