Frage von p4d3:
Hey Guys,
I am a newcomer in the HD world and would like to convert my recorded videos and editing.
I use ffmpegX and FCE and have reingeschaut synonymous in the Xilisoft converter.
My question relates primarily to the conversion. Can I convert my MTS files of my Panasonic HDC-SD10 without quality loss, without unnecessary with the memory requirements in the amount of shoot?
I have found out that I capture with 17Mbit / s AVCHD 1920 x 1080/50i format with MPEG4 Compression.
When I use the files to mp4 format with 17Mbit / s, a resolution of 1920 x 1080 convert I get artifacts in the mp4 files for converting to. Not mov format (; Xilisoft Converter).
I also wonder whether it is sufficient to choose a format (; MOV) to take the H264 codec and put the bit rate on my 17Mbit / s (; audio is currently something in the background), or is there something here that I've forgotten to consider?
Furthermore I am not sure if my 16GB SD card (; with a 10 on it), the 17Mbit / s received at all "may," or if I already have losses. Direct import of FCE has not worked out, he eventually stops the clips to import correctly (and my Case 102 Clips).
My best experience is currently a convert to MOV format with the MPEG 4 codec, 17Mbit / s and the 1920 resolution (; last test in Xilisoft Converter) and remove the filter "Skip" in FCE, which I improved the imperfections of interlaced.
Maybe you can send me your experiences and practices synonymous tell, would be very helpful.

You jump as merrily between codecs and wrappers and MPEG is MPEG 4 with 4 equally. I know this is confusing, but first of all, there are different MPEG4 "species" MPEG4 Part 10 and MPEG4 Part 2, Part 12, Part 14, etc. They all contain z.Tl. different codecs. If you now transfer AVCHD in a possibly different Wrapformat to change a codec can be connected to the case of identical bit rate has a significantly worse performance. An MPEG-4 so you can not see what you are altering. I would advise you not to re-encode AVCHD, AVC is because currently the most efficient codec, which is accessible to the consumer.
Others, like myself codecs, such as VC1 or x264 with less and other types of tools that similar, but in the end other tools available, so when transcoding after an identical quality this comes out. That may be now that you the differences as "not professional" may hardly notice, but they are there.
So you have only the choice between the worse results.
This affects the synonymous. Mov wrapper.
Keep My advice: you the original files without recoding somewhere, as long as Programs not natively with FCE can handle the codec.
As Arbeitsfile you can then encode into a format that meets your current needs. Count but with the fact that you have to use more data rate to approximately equal to achieve results.
If one day synonymous with such Programs can work around the formats you have at least the advantage of the high coding efficiency and no Transcodierartefakte.

Hello Wolfgang,
Thanks for the helpful info. I'm sorry if I durcheinanderwürfle everything here, I myself am often confused, what is what.
What would be a currently acceptable bit rate (in terms of quality UDN respect to the memory) when I avchd with 17Mbit / s memory?
My question is still synonymous if the CAMC. synonymous, the full 17Mbit / s can store on the SD card or the card if there already is too slow.
I will then back up to any event, once the files of the SD card as they are.
Antwort von Bernd E.:
... I'm not sure if my 16GB SD card (with a 10 on it), the 17Mbit / s received in general "may," or if I already have lost ... With a faster card of class 10 you will save time while recording to the computer, but when recording in the camera is such a smooth part of Overkill: Given the low data rate of the SD10 would be a class 4 SDHC card be enough. More detailed info to the way you can read in the manual.
... Direct import of FCE did not work ... Actually, this should be no problem and the synonymous Herumkonvertieren at random would make unnecessary: Which version of FCE are you using?

As I said, you should keep the original material as possible and refrain of a conversion.
If you carry it, but (for workflow reasons) yet, so you can orient yourself s.den bit rate is low, since AVC is such a thing as a "tool box" from which the Manufacturer may use different tools for image editing. So it's not as if one is to equate "more" s.Bitrate synonymous with a better Picture.
Another tool for example for the color processing can result in an inferior tool for motion estimation to the identical bit rate, but significantly different image impressions. (Also vice versa)
Therefore, the bit rate is only of limited value.
If you come but of AVC and MPEG2 encoded want to, there is the "number" of 30%
more data rate in order to get Picture an identical impression. If you like within the codecs (x264, VC1) umcodierst, which for me makes no real sense, you will need to compare the tools used.
Ergo: if you want to save bit rate, you do not succeed with transcoding, because you already used the most efficient codec.
Codierst you order, you should expect about 30%
more with.
If your source material that is 17 Mbit / s will get such you can not do without quality loss among them. However, synonymous here brings the increase of the bit rate with identical profiles / Level nothing.
AVC is as synonymous many other codecs, lossy. which means that your picture has been irreversibly reduced to a certain quality. This process is not to undo what codec and / or speed you use synonymous thereafter. But the quality is deteriorating by further transcoding.
So you should deal with such experiments only if it can not be avoided really.

Actually, this should be no problem and the synonymous Herumkonvertieren at random would make unnecessary: Which version of FCE are you using? The latest version, 4.0.1 I believe. I surrender synonymous not beaten quickly, to address what such things, but after many attempts and variations I've simply no explanation why he did not import cleanly.
The exact problem is this: FCE get the clips neatly converted and then starts to bring s.Fehlermeldungen some point (that little red exclamation mark next to the clip). When I use the clips, which could not be imported, import it works again, but then it happens that, for example clip 20 and clip 41 contains exactly the same video material.
I let the clips stored on external nerve. There in the folder as synonymous only 21-35 clip available (Finder are synonymous recognizes only the visible clip) when I eject the hard drive and then plug in again, diving to convert all the clips. Funny thing ...
