Looking for Data Rates for Apple AIC vs DV...

Question

I've been looking around for a chart that compares the storage needed for an hour of AIC at the various qualities.
I found this: http://support.apple.com/kb/HT2704   Please point me to the place of AIC Knowledge.
Thanx from Rosco

reading and writing the data shouldn't be the problem, its what you are doing with the data which will be taking all the time.
Try this
public class WriteFile {
    public static void main(String... args) throws IOException {
        String filename = "record.csv";
        int records = 140 * 1000;
        int values = 6;
            long start = System.nanoTime();
            PrintWriter pw = new PrintWriter(new BufferedWriter(new FileWriter(filename)));
            for (int r = 0; r < records; r++) {
                for (int i = 0; i < values; i++) {
                    if (i > 0)
                        pw.print(',');
                    pw.print(r * 10 + i);
                pw.println();
            pw.close();
            long time = System.nanoTime() - start;
            System.out.printf("Time to write %,d records was %.3f sec. file size=%.3fMB%n",
                    records, time / 1e9, new File(filename).length() / 1e6);
            long start = System.nanoTime();
            BufferedReader br = new BufferedReader(new FileReader(filename));
            String line;
            while ((line = br.readLine()) != null) {
                // do some work.
                String[] parts = line.split(",");
                int[] nums = new int[parts.length];
                for (int i = 0; i < parts.length; i++)
                    nums[i] = Integer.parseInt(parts);
br.close();
long time = System.nanoTime() - start;
System.out.printf("Time to read %,d records was %.3f sec%n",
records, time / 1e9);
PrintsTime to write 140,000 records was 0.462 sec. file size=6.193MB
Time to read 140,000 records was 0.792 sec
