Why in the world would you like to go back and record over the last clip? I recommend you NEVER EVER EVER erase a clip in the field. It is too easy to accidentally erase the wrong one.
Just tell the talent to count 3, 2, 1, and then start talking again.
Then when you are editing you through away the bad takes and piece together the good ones.

It doesn’t sound desirable, however, I have an NX5, so I cannot answer with experience. But it seems like your shoot is in a couple days so I will try.
You may try to turn off the data display on the camera. On the nx5 this turns off all the display items. It may temporarily turn off the menu going to the output device. Then make the change and turn the data display back on.

You are welcome.
1. Yes, those are synonym names for the nx5u.
2. Yes, the camera shoots in 24p natively.John

If and when I am in your shoes, I use file scavenger to recover bad files. Sometimes it works and sometimes it doesn’t.
I believe you can download trial version which will tell you if it can find any files on your media, before paying for it.
It has saved me on accidentally deleted hard drive files and I have used it on sd cards also. (It didn’t find anything since my shooter had not hit record on the camera in in the first place.)

Dean,
Welcome to the forum. I have four NX5Us and that support me and my family.I will answer some of your questions.
1. Do not buy a tape camera!!! The tape has many problems. I used to have problems just going from an indoor air conditioned place to outdoor humid place would cause momentary dropouts in the recording which then I had to edit around. The switch to memory cards is a monumental step away from that type of headache.2. Full High Definition has a screen size of 1920 wide by 1080 vertical. 24p means that it captures the entire image 24 times per second. 60p means it captures the entire image 60 times per second. 60p takes just over 2 times more data rate than 24p because it is doing it 60/24 times per second more.
3. 60i takes half the data rate of 60p because it records every other horizontal line as one image, then it records the opposite. The effect to the human eye is that it looks similar to 60p but at half the data rate of 60p.
4. Some cameras started to simulate 30p by telling the 60i to record the same image, then getting the odd rows and the even rows to come out sequentially. A good marketing ploy, but not really worth anything.
5. Some cameras started to simulate 24p by taking the 60i and simulating 30p, and then throwing away some of the frames. Often called pulldown. Thus it could be processed much as 60i, but during editing you would use the pulldown technique to get to 24p.
6. So, 24p native, simply means no tricks, the circuitry simply records the entire 1920 x 1080 24 times per second.
7. Now the next question is data rate in general. If the camera recorded every pixel times its pixel depth times 24 times per second, it would generate 1920 x 1080 x 36 ( number of bits to describe the color) x 24 frames per second = 1791 Megabits per second of data. That is so much data that every system uses a form of compression in order not to need an outrageous amount of storage.
8. The first compression technique is to not record all the color information for all the pixels.
9. In addition, the earliest compression technique was MPEG2 and is widely used.
10. The next compression technique is MPEG4 or AVC which looks the same as MPEG2 with have the amount of data.
11. The newest one is called AVC intra frame. This looks the same as AVC with the same data but is easier to edit with. I takes less computer power to decompress it.
All of these compression techniques are imperfect and create a less than perfect image. All things being equal more data means less compression means less imperfections in the image.

Bob,
I will respond. I don’t know what the issue is, however, I may offer some suggestions.
The camera itself records to a fat32 file system for compatibilty between macs and pcs and probably other reasons too. All cameras do. Fat32 has a file size limitation. When you are shooting in HD, the length of the clip will be 11:50 plus or minus. Then it starts a new clip.
When you use the software that comes with the camera to import it to your pc, the software stitches those clips together into the original length. If you just look on the memory card, you will see only clips around 11:50. You have to do the import.
Are you using the sony software utility to import?

Thank You everyone.
I used the vegasaur add on for the script.John

Thank You,
Before going the script route, I wanted to see if it could do it natively.
I take from your reply that Vegas cannot do it natively.

I edit in Sony Vegas Pro and often it works better with Sony camera source.
If you send me a few seconds of it I will put it in the timeline and see if 4 channels show up.

I assume that you are not supplying live feed to the TV outlet and are looking for something that they will be able to extract portions for airing.
I would should it 1920×1080 x 60i.
I usually use LPCM audio, when I am editing, but AC3 audio is more easily recognized.How the TV station wants the format is up to them, however, Most can ingest the AVCHD if you copy the whole file structure from the camera when you give it to them.
Sometimes I dual record onto SD card and onto the FM128 memory and hand the SD card to the client, or tv station in your case.
